Postpartum psychosis is a serious mental health illness that can affect someone soon after having a baby. It affects around 1 in 500 mothers after giving birth.

Many people who have given birth will experience mild mood changes after having a baby, known as the "baby blues". This is normal and usually only lasts for a few days.

But postpartum psychosis is very different from the "baby blues". It's a serious mental illness and should be treated as a medical emergency.

It's sometimes called puerperal psychosis or postnatal psychosis.
